ABSTRACT:
A process and a roll bending machine for bending plates. The plate to be bent is made to pass between upper and lower gripping rolls parallely arranged between each other; at least one of these rolls is connected to a drive motor for rotation. One of the rolls is upwardly movable to exert a required working pressure on the plate, and it is adjustably urged against the other roll in at least one intermediate position of its length till causing a deflection of both the rolls in the same direction, making one roll to assume an arch shaped configuration substantially conforming to the configuration of the other roll, in such a way to generate an homogenous bending pressure for the entire width of the plate which is thus bent with a substantially constant bending degree.
